Honeywell EM540 Tank Radar
The Honeywell EM540 Radar Type Level Gauge is an advanced marine-approved radar level measurement system engineered for accurate and reliable free-space cargo tank level monitoring onboard oil tankers, chemical tankers, offshore vessels, and marine storage facilities. Designed using intelligent 10GHz FMCW radar technology, the EM540 provides highly precise non-contact level measurement for hydrocarbons, chemicals, bitumen, and other liquid cargoes.
At Swift Marine Tech Services Pte Ltd, we specialize in the supply, installation, commissioning, calibration, troubleshooting, maintenance, repair, retrofit, inspection, and worldwide technical support for Honeywell marine tank gauging systems. Our experienced marine automation engineers ensure your vessel’s cargo monitoring system operates with maximum accuracy, reliability, and compliance.
Advanced Marine Radar Level Measurement Technology
The Honeywell EM540 uses an innovative planar antenna design with electronically shaped radar beams, removing the need for traditional horn or lens antennas. This advanced approach delivers stable, accurate, and dependable level measurement while helping to reduce maintenance needs and improve long-term operational reliability.
The EM540 works by transmitting a continuous frequency-modulated radar signal toward the liquid surface inside the tank. The reflected signal is then received by the antenna and processed by the gauge electronics to calculate the exact distance to the product surface. This non-contact measurement method ensures high accuracy even in demanding marine environments, where vapors, pressure changes, temperature variations, and tank movement can affect conventional level measurement devices.
The radar gauge continuously measures:
- Cargo tank level
- Tank pressure
- Temperature inputs
- System diagnostics
- Sensor health monitoring
All measurement data is transmitted securely to the vessel’s centralized cargo monitoring system through intrinsically safe digital communication, ensuring reliable integration with onboard automation and tank gauging systems.
